1. Patients can feel less pain:

2. Reduce the situation of bracket dropoffand ceramic bracket break:

3. Reduce arch wire fracture times:

NOW03 NOW04 Heat-Activated orthodontic Nitinol Arch Wire

Advantages：
 1. Patients can feel less pain: It derives from increasing force value and final light force.
Controlled heat-activity can event force value from increasing suddenly when patients drink hot  drink or eat hot food. Patients can relieve excessive force value by drinking cold water.
 2. Reduce the situation of bracket dropoffand ceramic bracket break: this is because the force is a kind of light force which can increase gradually. This kind of arch wire is ideal to
 ceramic bracket. Arch wire can keep its Martensite state under low temperature condition, which  is helpful to reduce initial force value and easy to keep arch wire.
 3. Reduce arch wire fracture times:
 4. Reduce working time at chair:.
 5. Shorten treatment time

The rigidity and form of S.S. preformed wires help to control arch form and the precise positioning of teeth.

ROUND ARCHWIRES
Round wires are used at the middle and last phase to stabilize the arch form
RECTANGULAR ARCHWIRES
Rectangular wires are used at fine adjustment phase
